Abstract
The analysis of the modern normative-methodological basis for determining anthropogenic damage to hydro-ecosystems, which has many significant drawbacks, is given. An alternative method of quantitative assessment of anthropogenic successions of hydro-ecosystems and the damage caused to them, based on the analysis of environmental risk, is proposed. The main characteristics of ecosystems were studied, the background values of environmental risk and the size of environmental risk in value terms were determined, scenarios of probable damage from construction and operation of the object and the model of the tree of dangerous events and their consequences were developed. The zone of potential influence of the object on the water areas - the zone where the risk values exceed the background level was singled out; the comparative analysis of the expected damage in the presence of several design solutions was carried out. The optimal solution is the one leading to the minimum damage.
